Ventilation, Daylight and Drainage Details

Accessories complete the roof and wall system of a pre-engineered building. Ridge vents, roof monitors, turbo vents and wall louvers provide different ways to plan airflow. Their location and fixing details need to be considered with the cladding layout so openings can be integrated into the building envelope.

Skylights and wall lights introduce daylight into the interior. Gutters and downspouts collect and direct rainwater away from roof edges and walls. The drawings on this page show how these parts relate to roof sheets, wall panels and supporting members; they also show why an accessory is more than an item added after the main frame is complete.

Selection depends on the building's use, roof arrangement, local conditions and maintenance access. Discuss ventilation, lighting and drainage needs during the initial design stage so the relevant openings, supports and fixing details are included in the project plan.
